Frame Skip & Stutter Test
Detect if your monitor is dropping internal frames when running at high refresh rates (144Hz, 240Hz, 360Hz) or custom overclocks.
Camera Pursuit Photo Grid
Take a 1/10s camera photo of the moving row below.
In your photo, you should see a continuous, unbroken sequence of adjacent lit blocks (e.g. 1 2 3 4 5 6 7 8). Every frame was displayed by your panel.
If your photo shows black missing gaps between lit blocks (e.g. 1 2 [GAP] 4 5 [GAP] 7), your monitor is failing internal frame delivery and dropping frames.
Frequently Asked Questions
What causes a monitor to skip frames? ↓
Frame skipping occurs when a monitor fails to display every frame sent by the GPU. This commonly happens when overclocking a monitor beyond its panel limits, using low-bandwidth DisplayPort/HDMI cables, or using unverified display custom resolutions.
How do I test for frame skipping with a camera photo? ↓
Start the pursuit grid test below, set your camera or smartphone camera to Manual/Pro mode with a 1/10 second (0.1s) shutter speed, and take a photo of the moving blocks. A healthy monitor shows a continuous row of lit blocks. A frame-skipping monitor shows black missing gaps between lit blocks.
How do I fix frame drops on my monitor? ↓
To fix frame drops: 1) Revert custom monitor overclocks to native panel refresh rate (e.g., 144Hz), 2) Upgrade to a VESA-certified DisplayPort 1.4 or HDMI 2.1 cable, and 3) Update your graphics card drivers.
Is frame skipping the same as low FPS? ↓
No. Low FPS means your GPU is generating fewer frames per second (e.g. 30 FPS game). Frame skipping means your GPU IS sending 144+ frames, but your monitor hardware drops frames internally, causing severe motion micro-stutter.
